Idler gear assembly for a generator

Abstract

An idler gear assembly for a generator includes a first gear configured for coupling to a second gear. The first gear includes a first shaft aligned along a first shaft axis, the first shaft having a first shoulder with a first axial face and a second shoulder with a second axial face diametrically opposed from the first axial face, diametrically opposed first and second grooves about a circumference of the first shoulder and a first set of teeth circumferentially located about the first shaft axis, the first shaft includes a first axial distance from the first axial face to the second axial face. The second gear includes a second shaft aligned along a second shaft axis, the second shaft having a diametrically opposed first and second tangs, and a second set of teeth circumferentially located about the second shaft axis, the second shaft includes a second axial distance.

Description

FIELD OF INVENTION[0001]This invention generally relates to an idler gear assembly for a generator and, more particularly, to a two-piece idler gear assembly for handling the expected stresses within the gear train of a generator oil supply pump.DESCRIPTION OF RELATED ART[0002]Systems that include electrical generators can include a hydraulic pump for cooling the generator or other components of the system. The pump can be driven by the rotor of the generator though a gear train. Misalignment of the gears within the gear train relative to the shaft, bearings, or other components, may increase wear on the gears and contribute to a reduction in gear durability. For instance, axial misalignment of the gears may cause uneven wear of the gear teeth and eventually necessitate replacement. Pressure pulsations from the pump may also contribute to premature wear of the gears. Often, it is a combination of both axial misalignment and pressure pulsation conditions that contribute to premature ...
